Water and Wastewater Innovations

Industrial water management is increasingly focused on minimizing discharge and maximizing reuse. Zero Liquid Discharge (ZLD) systems are a key example, combining membrane separation, thermal evaporation, and crystallization to eliminate liquid waste streams. These systems are particularly relevant for industries such as power generation, oil and gas, and chemicals.
Recent projects emphasize energy optimization and hybrid designs that reduce the high energy demand traditionally associated with ZLD. Innovations include better heat integration, improved brine concentration methods, and advanced control strategies.
For chemical engineers, ZLD systems represent complex, integrated process design challenges involving mass transfer, heat transfer, thermodynamics, and economics.
